It gives the plant air and food
Answer:
Option "C" Oxygen is the correct answer to the following question:
Explanation:
We know that, Just as a human absorbs oxygen into the body through inhalation, the oxygen enters into the whole body also in the blood and is used in the body by cells, so we can say that the human body needs a constant supply of oxygen. therefore, the appropriate option is true
Until now it is estimated U.S. coal production totaled about 9.1 million short tons (MMst) 27%lower than last year.
East of mississippi river totaled 3.7 MMst
West of mississippi river totaled 5.4 MMst
The supply of both types of coal is expected to decline as production from Appalachia falls from 201.5 million tons in 2018 to 170.1 million tons in 2020.
Answer:
20 chromosomes
Explanation:
Mitosis is a kind of cell division that results in daughter cells with same number of chromosomes as the parent cell. It involves stages including Prophase, Metaphase, Anaphase and Telophase. In prophase, the Chromatin condenses into Chromosomes.
In Anaphase stage, the 10 chromosomes as mentioned in the question divides into opposite poles of the cell. One individual chromosome contains two sister chromatids, which actually separates in the Anaphase stage. Hence, at the end of the Anaphase stage, there will be 10 chromatids each at opposite poles of the cell. Each chromatid at this stage is considered a chromosome.
Hence, a cell with 10 chromosomes will contain 20 chromosomes (10+10 chromatids on each pole) in the Anaphase stage just before the cell divides into two in a process called CYTOKINESIS.
